Rentals! That's the answer to all your problems. Rent out what you don't need and rent a few that you need to be competitive in Champion League (and in Brawls so you can win me a stack of those sweet Merits).

DEC payouts for matches are kind of low right now, so I'm finding it hard to be motivated to grind. I've mostly just been getting my Daily quest done and a couple extra matches and that's it. Especially on my alt accounts.
